1. 공정 엔지니어의 역할
공정 엔지니어의 역할은 고객의 요구사항 및 기술자료를 다른 전문가가 작업할 수 있도록 프로세스 설계로 변환하는 것입니다. 공정 엔지니어는 전체 프로젝트에 미치는 영향이 큽니다. 가장 기본이 되는 설계이기에 프로젝트 중간에 프로세스를 변경하면, 타 부서에서 변경하는 것보다 비용이 훨씬 더 많이 듭니다.
2. 공정 엔지니어가 작성할 7가지 기본 문서
공정 엔지니어는 다음의 7가지 문서에 대해 작성 합니다.
(A) Process Flow Diagrams (PFD)
(B) Equipment Datasheets
(C) Process Descriptions
(D) Equipment List
(E) Piping & Instrument Diagrams (P&ID)
(F) Process Information Data Sheets
(G) Duty Specification
각 문서에 대한 특징은 아래와 같습니다.
A. The Process Flow Diagrams are primarily a communication of the general process design to the client for his review, comments, and approval. After it is approved, it is used by:
1) Piping and plant layout to establish the equipment arrangement and building requirements.
2) Instrument Engineering as a basis for their input to P&ID’s.
3) Other groups to scope the work to be done.
4) Preparation for Equipment process data sheets.
B. The Equipment Datasheets are used to provide detailed information for detail design of major equipment, and to summarize specific process information.
Mechanical Data Sheets are prepared by Process Engineers and contain specifications of major process equipment (vessels, pumps, heat exchangers, etc.). Based on the information in these data sheets, the Mechanical Engineering prepare inquiries, select vendors and issue requisitions for the equipment,
C. The Process Descriptions are fundamental to the system design approach that the function, design bases, operating modes, and principal features of systems be established at an early point in the design effort, preferably while considering general plant criteria.
D. Equipment Lists are prepared by Process Engineers to coordinate the process equipment. All process major equipment should be listed in these lists. The detailed specification will be filled up by mechanical dept., electrical dept. and procurement dept. and used as reference information and check list for other dept.
E. Piping and Instrument Diagrams (also called Engineering Flow Diagrams) are prepared jointly by the Process Engineering and Instrument Engineering Groups, and contain the detailed specifications required by Piping, Mechanical, Electrical, and Instrument Engineering.
F. Process Information Datasheets are prepared by process engineers to summarize process information for other specialists, e.g., Piping, Instrumentation, Environmental, etc.
G. Duty Specifications are prepared by process engineers to define the process requirement of package system.
These Duty Specifications are used to provide project specification for procurement of packaged system.
